Student drawings portrayed the heart-wrenching images, some with speech bubbles saying, "help," "I love you" and "one way ticket to heaven." Gremillion tells KFOX-TV that the classroom teacher also told her students that "the Afghans did this because they hate all of us and want to kill all of us."

One student, Gremillion says, was under the impression that the tragedy occurs every September 11 and was too afraid to leave his house to go to school.

In a statement, El Paso Independent School District said they are investigating the allegations. From KDBC:

"EPISD is very concerned about the images that were drawn in response to a lesson on the events of September 11th. District and campus administrators are investigating the specific assignment and are interviewing the personnel involved. We regret the insensitivity that this action may have caused and wish to assure our community that we will act swiftly in this matter and will take any and all appropriate action. We extend our sincere apologies."

A similar incident in California sparked outrage in June, when a student-made sign at Fresno's Hamilton Elementary School depicted Jesus with a caption reading, "I want you to kill all the infidels" and "meet me in Jerusalem, get a free ticket to heaven."

The sign was made by a seventh-grade student as part of an assignment for a history unit on the Crusades. The term "infidel" was used at the time to describe those not of the Christian faith and being targeted for conversion.
